Interventional radiology (IR) refers to the special practices performed under the minimally invasive treatment procedure. It uses image guidance technology to find more precision in the treatment. Such images are considered to direct the treatment procedure that may include the use of needle or other tiny instruments like small tubes or catheters. So the interventional radiologist can find a lager assistant to direct these instruments through the body to the area of damaged parts. This particular technique has really proved to be helpful to diagnose some of the most perilous diseases including cancer. Its methods are done purely for diagnostic purposes per se angiogram.
The IR technique uses some common interventional modalities like fluoroscopy, magnetic resonance imaging (MRI), computed tomography (CT), ultrasound scanner. Fluoroscopy and CT use ionizing radiation to find fast and geometrically accurate treatment. MRI technique is also capable to provide superior tissue contrast, but it requires a specialized instrument, therefore it is a little expansive for the patients.
There are some common procedures for which interventional radiology techniques is performed. Some of the procedures are as-
Angiography - it is the X-ray imaging of blood vessels to identify blockage or narrowing of the vessels. With the help of IR images, physicians can insert a small stent to inflate and open the blocked vessels.
Balloon angioplasty/stent- here doctor uses a small balloon on the tip of the catheter to widen the narrowed vessel.
Embolization - it includes the insertion process of a substance through a catheter into the blood vessel to check hemorrhaging, or excessive bleeding.
Chemoembolization - under this method, the treatment is directly given to a tumor through its blood supply. It uses clot-inducing substance to check blood flow in the artery.
Needle biopsy - here a small needle is inserted into the damaged part of the body, guided by imaging techniques. Such biopsy can be performed without surgical intervention.
Catheters insertions - in this process a catheter is inserted into large vein for delivering chemotherapy drugs, nutritional support, and hemodialysis. The catheters can be divided into five types, such as diagnostic angiographic catheters, micro catheters, drainage catheters, balloon catheters, central venous catheters.
The radiology treatment needs a team of well qualified physicians deliver more precision in the interventional radiological treatment procedures. So that the fatal diseases like cancer can be cured successfully.
